Cyclone technologies for efficient size mass and density

"When multi-density particles enter the mix, then a hydrocyclone, in essence, separates based on mass. With homogeneous ores, mass and size are directly related, because bigger particles always have bigger mass, so we can still use the term cut-size to describe the separation process. But when the densities are different, this is not the case.
